Spherical pixelization schemes are reviewed for analyzing extended emission, and in particular for investigating the cosmic microwave background. Problems with implementing different schemes are considered. The nonhierarchical Gauss — Legendre sky pixelization (GLESP) approach is discussed in detail.
